The Three Hundred project: Estimating the dependence of gas filaments on the mass of galaxy clusters
Sara Santoni, Marco De Petris, Gustavo Yepes +7
Galaxy clusters are located in the densest areas of the universe and are intricately connected to larger structures through the filamentary network of the Cosmic Web. In this scena…

The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide valuable opportunities for forthcoming galaxy surveys through their huge multiplexi…
Enabling discovery of gravitationally lensed explosive transients: a new method to build an all-sky watch-list of groups and clusters of galaxies
Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +4
Cross-referencing a watchlist of galaxy groups and clusters with transient detections from real-time streams of wide-field survey data is a promising method for discovering gravita…
On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo
Matteo Bianconi, Graham P. Smith, Matt Nicholl +7
We search for gravitational wave (GW) events from LIGO-Virgo's third run that may have been affected by gravitational lensing. Gravitational lensing delays the arrival of GWs, and…
Discovering gravitationally lensed gravitational waves: predicted rates, candidate selection, and localization with the Vera Rubin Observatory
Graham P. Smith, Andrew Robertson, Guillaume Mahler +7
Secure confirmation that a gravitational wave (GW) has been gravitationally lensed would bring together these two pillars of General Relativity for the first time. This breakthroug…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
Pilot-WINGS: An extended MUSE view of the structure of Abell 370
David J. Lagattuta, Johan Richard, Franz Erik Bauer +18
We investigate the strong-lensing cluster Abell 370 (A370) using a wide Integral Field Unit (IFU) spectroscopic mosaic from the Multi-Unit Spectroscopic Explorer (MUSE). IFU spectr…
Extensive Lensing Survey of Optical and Near-Infrared Dark Objects (El Sonido): HST H-Faint Galaxies behind 101 Lensing Clusters
Fengwu Sun, Eiichi Egami, Pablo G. Pérez-González +22
We present a Spitzer/IRAC survey of H-faint (, ) sources in 101 lensing cluster fields. Across a CANDELS/Wide-like survey area of 648 arcmin (e…

Matteo Bianconi, Riccardo Buscicchio, Graham P. Smith +4
We present the direct detection of the splashback feature using the sample of massive galaxy clusters from the Local Cluster Substructure Survey (LoCuSS). This feature is clearly d…
Constraining the lensing of binary black holes from their stochastic background
Riccardo Buscicchio, Christopher J. Moore, Geraint Pratten +3
Gravitational waves (GWs) are subject to gravitational lensing in the same way as electromagnetic radiation. However, to date, no unequivocal observation of a lensed GW transient h…

Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +3
Motivated by discovering strongly-lensed supernovae, gravitational waves, and kilonovae in the 2020s, we investigate whether to build a watch-list of clusters based on observed clu…
What does strong gravitational lensing? The mass and redshift distribution of high-magnification lenses
Andrew Robertson, Graham P. Smith, Richard Massey +4
Many distant objects can only be detected, or become more scientifically valuable, if they have been highly magnified by strong gravitational lensing. We use EAGLE and BAHAMAS, two…
LoCuSS: exploring the connection between local environment, star formation and dust mass in Abell 1758
